Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve the durability of a shoe of a liquid pressure rotary machine.SOLUTION: A piston pump motor 100 is equipped with: a cylinder block 2 rotated with a shaft 1; a piston 6 slidably inserted in a cylinder 2b formed on the cylinder block 2; a shoe 20 which is rotatably coupled at a tip end portion of the piston 6, and slides the tip end portion; and a swash plate 8 with which the shoe 20 slides. The shoe 20 has a piston slide potion 30 sliding with the piston 6 and a swash plate slide portion 31 sliding with the swash plate 8; a shoe body portion 21 to which the piston slide portion 30 and the swash plate slide portion 31 are attached; and a first locking portion 40 and a second locking portion 50 which are respectively provided between the shoe body portion 21 and the piston slide portion 30 and between the shoe body portion 21 and the swash plate slide portion 31, and respectively regulate the relative rotation between the shoe body portion 21 and the piston slide portion 30 and between the shoe body portion 21 and the swash plate slide portion 31.SELECTED DRAWING: Figure 2
